摘　　要：基于砂加气混凝土砌体的承重性能试验数据,利用ABAQUS有限元软件,进行墙体构件的承重及抗剪性能模拟分析,探求适用于砂加气混凝土砌块承重结构体系中的墙体结构型式类型,得到了经济合理墙体高厚比、墙体加筋率和构造柱间距等设计参数。提出增加结构整体性和刚度的构造措施,对砂加气混凝土在砌体结构承重体系的工程应用提供参考。Based on the load-bearing experiment of autoclaved aerated concrete, a numerical simulation was conducted in this research, which analyzed the load-bearing and shear behavior of general wall components by ABAQUES software, and the reasonable structural types of AAC bearing wall were discussed. Quite a few economical and reasonable design parameters were acquired, which contained depth- thickness ratio of the wall, rate of reinforcement of the wall, and the spacing between the constructional columns. Then some structural measures were proposed, which could increase integrity and stiffness of the structure. Consequently, this research was beneficial to the engineering application of the autoclaved aerated concrete in load-bearing structure.
